This invention relates to a seeding machine, and it consists in theconstructions, arrangements and combinations herein described andclaimed. kIt is an important object of the invention to provide aconstruction of machine` for broadcasting ofY brome grass seed,`although not limited thereto, the uniform distribution of which iseffective under forward motion of the machine.

More specifically, it'is an object of the inven-v tion to provide awheeled frame structure upon whichv there is mounted a transverselydisposed seed hopper, having means in the base thereof for discharge ofseed the means being in the form of a'reciprocating chain'elementactuated by mechanism operatedthrough one ofthe Wheels of the machine.

. Itis also an importantobject of the invention constructed inaccordance withthe invention. a

portion of the hopper beingbroken away, to il-` lustrate certainoperating, mechanism.

Figure 2 is a cross section on the line 2-2 of Figure 1'.

Figure 3 is a rear elevation of the machine.

Figure 4 is an enlarged cross section through the hopper,

Figure 5 is an enlarged fragmentary perspec tive of the seed distributerbase.

Figure 6 is an enlarged detail perspective of the seed distributerchain.

Figure 7 is a side elevation of an eccentric emplcyed in the machine forvaryingthe travel of the distributer chain.

There is illustrated a frame I0, which may be formed from channel iron,consisting of side stringers II, connected at their ends by a frontstringer I2 and a rear Stringer I3. As may be seen in Figures 2 and 3, apair of depending brackets I 4 are secured to thev underside of the rearI6 extending transversely beneath the frame structure generally, atrussed "rod I'Iy is secured and extended between the lower ends of( thedepending brackets III.Y v

The bearing brackets YI5V may be welded or bolted to the brackets I4 andmaybe additionally supportedby brace rods l 8` secured' thereto and 'tothe sidesof stringersv II. i 'ffl A draft tongue I9 is secured mediallyof theifrarne, being bolted or otherwise secured to'th'e" front stringerI2 and the rear Stringer I3.

An operators seat 20 is also located medially of the frame, bolted tothe rear end of the draftl tongue I9.

The forward portion of the frame IQ is braced.v by a rod 2| fixedbetween the 'side stringers'fII as shown in Figure l. l Vf A tractionwheel '22 is loosely mounted upon respective ends of the axleV I-S, thatwheel posi'- i tioned upon the right of the frame as yViewed from= therear, being provided with a hub extension 23 upon which there is xed asprocket 24 for operating the seed distributer mechanism, as'will now bedescribedj* i Upon a forward portion ofthe frame I0; e1:- tendingtransversely thereof, a seed hopper25'is mounted. of a length sol as toextend beyond the l sides of the frame. Thehopper 25`consists of adistributer base-26 provided with a 'plurality o1"5- openings 2l spacedlongitudinally ofthe base' through which seed will be discharged. Asshown, the openings are of tapered formationfthe larger opening ,beingpresented to the underside` of Athe, base, while Athe. smaller openingis presented upon'. the base of` a channel 28 formed in the distributerbbasef26.l At respective sides jof the channel 28x'` cylindrical guiderods 29 are secured for support of a feeder chain 30. The chain 30consists of a plurality of links hingedly connected together, the linksbeing of a width to present respective side frame pieces 3| directlyupon the guide rods 29, as may be seen in Figure 4'. A verticallydisposed plate'k 32 is secured to every fifth link of the chain, for apurpose presently to be explained. rIhe hopper 25 is the same length asthe base 25 and has inwardly tapered sidewalls 33 terminating at theside portions of the channel 28. 'I'he channel 28 opens upon respectiveends thereof for passage of the chain therethrough, and rockablysupported in bracketsy 34 at the ends of the base 26 there is a sectorgear`35. The ends of the chain are connected to respective gears as maybe seen in Figure 3. The gears 35 are each supported upon a shaft 36 `to,which 'a crank 3l is secured. The crank 31 associated with the shaft tothe right ofthe machine .has

pivotally connected thereto a link 38, while the crank t the left hasconnected thereto a link 38'. The link 38 is pivotally connected to oneend of a draft link 39 reciprocably mounted in a dual bearing 40 fixedupon the base 26. The other end ofthe draft link is pivotally connectedto a link 4|, the latter being threadedly engaged in one end of a turnbuckle, 42. The other end of the'turn buckle threadedly receives thelink 38'.

It will beunde'rstood that by adjustment of the turnbuckle, tension onthe distributor chain 30 may be varied, as well as toaccommodate forwear.

A transverse beam 43 is mounted upon the Y frame I0 rearwardly of thehopper 25, and upon this beam a gearing bracket 44 and Va clutch bracket45 are secured. The gearingv bracket consists of a'bearing 46 `forsupport of a shaft 41 and a bearing 48 disposed at right angles toconnected to :theedraft link 39 as indicated at 55.

The shaft 4l is 'further support'edby a bearing 56iandfthe outer end ofthe shaft 41 hasxed thereon a sprocket 5'! aligned. with the sprocket 24and about these sprockets there is trained a chain 58.y Upon the shaft41a clutch device 59 is mounted operable by means of a hand lever 607within reach of the operator of the machine.

, In. operation, it will be seen that upon forward movement` of themachine with the clutch 59 engaged, to and fro `movement of the chain 39will be effected and under such movement seed within the hopper 25 willbe agitated and the 'plates' 32will move the seed for discharge throughthe openings 21 of the base4 26for discharge to the ground. Y f

While I have shown and-described a preferred form-'0f the device, thisis by4 way of illustration only, and I. consider as my own all suchmodifications-in `construction as fairly fall within the scope of theappendedr claims.
